The cables C1 and C2 are drawn into the passage 10 of the duct 1 so that the wiring operation can be easily performed. The same can be applied to pipes such as electric conduits.

[0009], in the wiring and piping ducts according to claim 1, 2, since by recessed outer peripheral wall of the duct bis insertion groove is provided, as shown in FIG. 6 or FIG. 7 A mounting hole 61 provided in the mounting piece 60 of the lighting fixture G, or a screw insertion hole 6 provided in the bottom wall of the wiring box B.
By inserting the screw 20 through the screw 2 and screwing it into the screw insertion groove 12, a fixture such as a lighting fixture can be easily attached. In addition, since the passage portion 10 in the duct 1 is partitioned by the screw insertion groove 12, as shown in, for example, FIG. 3 or FIG. 5, the cable C1 for weak electricity and the cable C2 for strong electricity can be stored separately. I can do it. Therefore, the wiring and the piping can be arranged, and the work of drawing out the cable and the like after the wiring and the piping can be easily performed.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 to 8, an embodiment embodying a wiring / piping duct according to the present invention will be described in detail.

As shown in FIG. 1, the wiring / piping duct 1 is made of a metal such as aluminum or a synthetic resin, and is formed in a rectangular tube shape as a whole, and a passage in which a cable or a pipe is housed. It has a part 10.

One side of the duct 1 has a passage 10
Is formed continuously in the length direction. The narrow opening 11 is formed with a width smaller than the diameter of the cable or the pipe. Therefore, the cables and pipes stored in the passage 10 do not fall out.

On the opposite side of one side surface of the duct 1 in which the narrow opening 11 is formed, a screw insertion groove 12 is formed in which the outer peripheral wall is recessed and is continuous in the length direction. As shown in FIG. 2, the screw 20 can be screwed into the screw insertion groove 12 and fixed. As a result, the fixture 30 such as a lighting fixture or a wiring box is connected to the screw 2.
0 can be attached to the wiring / piping duct 1. The passage portion 10 is partitioned by the screw insertion groove 11. As shown in FIG. 3, the passage portion 10 is housed in the passage portion 10 separately, for example, into a cable C1 for weak electricity and a cable C2 for strong electricity. Is available. Note that the screw insertion groove 12 is
It is not limited to the case where they are provided continuously in the length direction of the duct 1, and they may be provided at predetermined intervals in the length direction of the duct 1.

When a cable is drawn in and routed in the wiring / piping duct 1 shown in FIG. 1, for example, as shown in FIG. 3, a plate 42 provided with a protruding portion 43 for connecting a connecting rope 50 and a duct 1 The cables C1 and C2 are connected to the protruding portion 43 of the plate 42 by a connecting rope 50, and the handle 41 is connected to the duct 1 by a retractor 40 comprising a thin plate-like handle 41 which can pass through the narrow opening 11 provided in the duct 1. When the worker pulls the retracting tool 40 along the narrow opening 11 in a state where the cable C1 and C2 are projected outside the narrow opening 11, the cables C1 and C2 are drawn into the passage portion 10 of the duct 1 in a divided state and wired. can do. The same can be applied to the case where a pipe such as an electric conduit is drawn in and piped.

A cable C is provided in the passage 10 of the duct 1.
1, C2 and pipes are drawn in and wired and piped, in addition to the drawing tool 40 shown in the figure,
A retracting tool having a locking projection with a bifurcated tip at the end so as to straddle a partition formed to protrude inside may be used. Further, a drop rope is connected to one end of each of the cables C1 and C2 and the pipe, and the other end of the pull rope is connected to the narrow opening 11 of the duct 1.
The cables C1 and C2 and pipes may be drawn into the passage portion 10 of the duct 1 and wired and piped by protruding and pulling them outward.

In the case of the wiring / piping duct 1 shown in FIG.
A narrow opening 11 is formed on one side of the duct 1, and a screw insertion groove 12 is formed on the opposite side of the side of the duct 1 on which the narrow opening 11 is formed.
This is because it is most convenient for wiring and piping in a state where cables and pipes are sorted by 0 or the like.

When mounting the lighting fixture G,
As shown in FIG. 6, a mounting piece 6 provided on the lighting fixture G is provided.
The screw 20 is inserted through the mounting hole 61 of the “0”, and the screw 20 is screwed into the screw insertion groove 11 of the duct 1. In this case, knockouts 13 may be provided on the lower surface of the duct 1 at predetermined intervals, and the cable C may be pulled out from an appropriate position.

As shown in FIG. 7, when the wiring box B is mounted, the screw 20 is inserted into the screw insertion hole 62 provided on the bottom wall of the box B, and the screw insertion groove 11 of the duct 1 is further inserted. Screw the screw 20. Thereby, the lighting fixture G and the wiring box B can be easily attached.

FIG. 4 shows another embodiment of the wiring / piping duct according to the present invention. The wiring / piping duct 1 has an outer peripheral wall recessed on one side of the duct 1 and extends in the longitudinal direction. A continuous screw insertion groove 12 is formed, the top of the screw insertion groove 12 is opened, and this opening is formed as a narrow opening 11. The screw insertion groove 12 is formed with a groove width capable of screwing and fixing the screw 20, and the narrow opening 11 is formed with a width smaller than the diameter of the cable or the pipe. In this example, the width of the screw insertion groove 12 and the width of the narrow opening 11 are formed to be the same width, but may be formed to have different widths as long as the above conditions are satisfied.

In the case of the wiring / piping duct 1 shown in FIG. 4, for example, as shown in FIG. 5, a plate 42 provided with a projecting portion 43 for connecting a connecting rope 50 and a narrow width provided in the duct 1 Thin handle 4 that can pass through opening 11
1, the cables C1 and C2 are connected to the protruding portion 43 of the plate member 42 by the connecting rope 50, and the handle 41
The operator pulls the retracting tool 40 along the narrow opening 11 in a state in which the cable C1 projects outside the narrow opening 11 of the duct 1, so that the cable C <b> 1
C2 can be drawn in and wired in a divided state. The same can be applied to the case where a pipe such as an electric conduit is drawn in and piped. When the cables C1, C2 and pipes are drawn into the passage 10 of the duct 1, one end is connected to the cables C1, C2 and pipes, and the other end is connected to the narrow opening 11 of the duct 1 in addition to the pull-in tool 40. A retracting rope that protrudes more outward may be used. Then, similarly to the case of the wiring / piping duct 1 shown in FIG. 1 described above, the lighting fixture G and the wiring box B are easily attached by fixing the screws 20 to the screw insertion grooves 12 of the wiring / piping duct 1. be able to.

[0021]

As described above, in the wiring and piping ducts according to the first and second aspects, the removal and installation work of the cover body as in the conventional wiring and piping duct is not required, and the outside is not required. And the duct passage are connected to each other, and a narrow opening that is continuous in the length direction is provided. By using this, it is possible to efficiently perform the wiring work of the cable or the piping work of the electric conduit and the like. Since the outer peripheral wall of the duct is recessed and the screw insertion groove is provided continuously in the length direction, it is possible to easily attach the fixtures such as lighting fixtures and to perform the attachment work efficiently. it can.
In addition, since the passage section in the duct is partitioned by the screw insertion groove, the cables can be sorted and stored by type, so that the wiring and piping can be arranged and the wiring and piping can be arranged.
This has the effect that the work of pulling out cables and the like after piping can be easily performed.
